What Our Gearhead(R) Experts Are Saying:"I took the Ozone Exp Carry On Hardside 4W Bag through three connecting flights last month, and it held up without a scratch. The ZeroLiner interior gave me noticeably more packing room than I expected, and those Hinomoto wheels made sprinting between gates feel effortless."The gate agent calls your boarding group, and you're already rolling. The Osprey Ozone Exp Carry On Hardside 4W Bag is the carry-on for people who move fast and check nothing, built from a 70% recycled Makrolon polycarbonate shell that takes the knocks of overhead bins and baggage carousels without showing a single mark. Inside, the ZeroLiner construction strips away traditional lining to give you more usable space and a cleaner interior that wipes down in seconds. Interior fabric dividers help you keep your essentials sorted from the moment you zip up at home to the moment you arrive at your hotel. The 60mm Hinomoto Silent Run dual spinner wheels glide in any direction, and a TSA-approved Travel Sentry lock with YKK EYL zippers means you can hand it off to an agent and not think twice.
